You can use the Thunderbird mail client in offline mode even with a IMAP email account such as you ITET account.
In Thunderbird go to File > Offline > Offline Settings. Check the the first box which will make message in your inbox available in offline mode. You may also check the second box if you so desire.
Furthermore, click on Select folders for offline use..., which allows you to choose which folders of your account will be made available when working offline.
Click OK} and go to File > Offline > Work Offline. You will be asked whether you want to download your messages for offline use. Click Yes.
You may now disconnect your computer from the internet and write/delete/move messages as you like. Note that when composing a new message there is no longer a Send button. However, there is a Send Later instead.
Once you have finished working offline. Go to File > Offline > Work Offline. If you composed messages while offline, you will be prompted to confirm the sending of those messages.
- Apart from sending new messages, all other changes you made while offline will be synchronized now, lest the IMAP server is up to date. The status of the synchronization is displayed at the bottom of the thunderbird main window.
